Enum mz_repr::global_id::GlobalId

pub enum GlobalId {
    System(u64),
    User(u64),
    Transient(u64),
    Explain,
}

The identifier for a global dataflow.

WARNING: Despite the fact that GlobalId implements Ord, the ordering of IDs does not express any relationship between dependencies. We retain the Ord implementation exclusively to facilitate placing GlobalIds in maps/sets.

Variants

System(u64)

System namespace.

User(u64)

User namespace.

Transient(u64)

Transient namespace.

Explain

Dummy id for query being explained

Implementations

impl GlobalId

pub fn is_system(&self) -> bool

Reports whether this ID is in the system namespace.

pub fn is_user(&self) -> bool

Reports whether this ID is in the user namespace.

pub fn is_transient(&self) -> bool

Trait Implementations

impl Arbitrary for GlobalId

type Parameters = (<u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Union<BoxedStrategy<GlobalId>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for GlobalId

fn clone(&self) -> GlobalId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Columnation for GlobalId

type InnerRegion = CloneRegion<GlobalId>

The type of region capable of absorbing allocations owned by the Self type. Note: not allocations of Self, but of the things that it owns.

impl Debug for GlobalId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GlobalId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GlobalId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for GlobalId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for GlobalId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MzReflect for GlobalId

fn add_to_reflected_type_info(rti: &mut ReflectedTypeInfo)

Adds names and types of the fields of the struct or enum to rti.

impl Ord for GlobalId

fn cmp(&self, other: &GlobalId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<GlobalId> for GlobalId

fn eq(&self, other: &GlobalId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<GlobalId> for GlobalId

fn partial_cmp(&self, other: &GlobalId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl RustType<ProtoGlobalId> for GlobalId

fn into_proto(&self) -> ProtoGlobalId

Convert a Self into a Proto value.

fn from_proto(proto: ProtoGlobalId) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

impl Serialize for GlobalId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
